Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for producing a decorative veneer that produces a unique pattern on the board surface.

[Background technology]

Conventional decorative veneer manufacturing methods mainly aim to artificially express the grain pattern or straight grain pattern of natural wood species, and in order to obtain decorative veneer with high fidelity to natural wood species, the method of manufacturing decorative veneers is A plurality of sheets were laminated with adhesive and pressed together to obtain an assembled flitch, which was then sliced to create the desired decorative veneer.

[Purpose of the invention]

An object of the present invention is to provide a method for manufacturing a decorative veneer that expresses a unique pattern that has not been seen before.

[Disclosure of the invention]

The method for producing a decorative veneer of the present invention is to randomly laminate a plurality of colored veneers of different colors, press and bond them together to obtain a primary flitch, and intersect this primary flitch with the laminated surface. Sliced veneers are created by slicing from different directions, with different colors arranged side by side at random on the sides, and the sliced veneers are laminated with the sides aligned and offset from each other in the front and back directions, and then bonded by pressure to form a secondary assembly. A decorative veneer in which different colors are randomly arranged in the vertical and horizontal directions of the board surface is obtained by obtaining a flitch and slicing this secondary assembled flitch.

Figures 1 (A) to (E) show the method for manufacturing a decorative veneer of this invention.
The explanation will be based on. First, as shown in the same figure (A), a plurality of colored veneers 1a of different colors are obtained by dyeing a material veneer,
Create lb and lc. These colored veneers are randomly combined and laminated and pressure bonded to form the primary assembled flitch 2.
((B) in the same figure). The colored veneers 1a, lb, and lc are randomly combined using, for example, a random number table.

Pressing is performed using a flat mold (not shown).

Next, the primary flitch assembly 2 is cut diagonally at a predetermined inclination angle θ in the fiber direction (indicated by arrow A), as shown in FIG.
A block body 3 shown in is obtained. This block body 3 is shown in the same figure (
The sliced veneer 4 as shown in FIG. 2D is created by slicing from the direction intersecting the laminated surface as shown by the two-dot chain line in C).

This sliced veneer 4 has different colors juxtaposed at random over its entire circumference. This sliced veneer 4 is shown in the same figure (
As shown in E), the secondary assembled flitch 5 is obtained by stacking and bonding with the side surfaces coincident and arbitrarily shifted in the front-back direction. By slicing this parallel or diagonally to the side,
A decorative veneer 6 with a unique pattern in which different colors are randomly arranged in the vertical and horizontal directions of the board surface is obtained.

The colored veneer is not limited to only three types as shown in FIG. 1(A), but two or more types of colored veneer can be used. In addition, the cutting angle θ of the primary flitch assembly 2
By changing , it is possible to arbitrarily determine the pattern unit length a shown in the decorative unit VI6 shown in FIG. In addition, by changing the thickness t of the sliced veneer 4 shown in FIG. 4C, the width shown in FIG. In this way, it is possible to create decorative veneers with a wide variety of unique patterns.

In the above explanation, the primary flitch assembly 2 is set at a predetermined angle θ.
Although the block body 3 was created by cutting the block body 3, the sliced veneer 4 may be created by slicing the primary assembled flitch from the direction intersecting the laminated surface without creating the block body 3. In this case, different colors are randomly arranged side by side only on the side surfaces of the sliced veneers 4. This sliced veneer 4 is laminated in the same manner as described above and bonded by pressure to form a secondary assembled flitch 5.
A similar singular pattern can be obtained by slicing this.

Next, the present invention will be explained in detail by giving examples.

Example: A 1.0 yen thick Rokuri veneer (Chinese wood) was dyed in equal numbers in three types: blue, yellow, and red using tank dyeing. These veneers were dried to a bone-dry moisture content of 20 to 30% to produce each colored veneer JIi (blue...A, yellow...B, red...
・C) are randomly combined and laminated via a wet adhesive and pressure bonded to obtain a primary assembled flitch. The combination is AB
There are 6i111 C sequences (ABC, ACB,

A wet adhesive was used as the adhesive and applied at a coating weight of 100 g/rd. Further, the laminated veneer was pressure-molded in a flat mold at 10 kg/cXa.

Then, as shown in FIG. 2, the primary flitch assembly 2' was cut at an inclination angle θ of 6.5°. As shown in FIG. 3, the obtained block body 3' was sliced to a thickness of 1.8 am to obtain a sliced veneer 4'. As shown in FIG. 4, the sliced veneers 4' were stacked on top of each other in a mutually shifted manner and bonded together by pressure. To shift the sliced veneer 4', set the shift τF method to 0.

With the above combination, 30 sheets were set as one cycle, and the cycle was repeated to shift the number of sheets. Use wet adhesive for adhesive, 1
The coating was applied at a weight of 0.00 g/rd and press molded in a flat mold at a weight of 10 kg/-. The obtained secondary assembled frift 5' was vertically sliced to obtain a decorative veneer with a unique pattern.

〔Effect of the invention〕

According to this invention, it is possible to create a decorative veneer having a unique pattern never seen before in which a plurality of different colors are randomly arranged, and also to change the slice thickness and angle of the primary flitch and secondary flitch. By changing , there is an effect that various patterns can be made to appear.

Claims (1)

[Claims] Multiple types of colored veneers with different colors are randomly laminated and pressure-bonded to obtain a primary assembled flitch, and this primary assembled flitch is sliced from the direction intersecting the laminated surface, with different colors randomly on the sides. Create sliced veneers arranged side by side, stack the sliced veneers so that their sides match and shift the front and back directions mutually, press and bond them to obtain a secondary assembled flitch, and slice this secondary assembled flitch. A method for manufacturing a decorative veneer, which obtains a decorative veneer in which different colors are randomly arranged in the vertical and horizontal directions of the board surface.
